  • External harddrive not recognised

    Hi.. im not sure if this is the correct forum, but i'll give it a shot. I have a hard drive I used in a windows pc. I recently bought a mac compatible external usb hdd casing and fitted the hard drive. But when I connect to my powerbook g4, it is not recognised by mac. Its shows up as connected in disk utility but its not mapped.... any help please????

    Because USB isn't bootable, most people stick to Oxford 911+ which has FW400 and USB2 support.
    You can find "Mac-compatible FireWire" for $38 on Amazon or just head to
    http://www.macsales.com and see what is in the sales specials.
    Also, you may want to remove the partition table while connected to PC, or try booting from Tiger DVD and wipe the drive.

  • 1.5TB external HDD not recognised on various laptops

    Hi,
    I was wondering if anyone could help me.
    I bought my toshiba 1.5 terrabyte external harddrive just over a year ago. It works fine on my other laptop and my boyfriend's laptop but when I connected it to four other new laptops (all different brands) recently it was not recognised on these laptops at all.
    Is there something wrong with my external or is something on these computers blocking it from being recognised? Do you know how I can fix this problem?
    Many Thanks!

    Hello
    And if you connect the external HDD to your and boyfriends notebook everything is still ok? You have only problems with new notebooks?
    Well thats really strange Have you tested another USB cable and different USB ports?
    Maybe on the new notebooks the antivirus or firewall program is blocking the access to external drive. Check your security software and allow external devices.

  • External HDs not mounting

    My OP is Lion 10.7.5. I have two external HDs: one LACIE 1T which I use for Time Machine and a IOMEGA 500M which I use for my photos. Both of them stopped mounting when I upgraded to Lion. I can see them both in Disk Utility but  grayed out. They both Verify fine in Disk Utility. When I tried to mount them with disk utility it does not work. I have tried everything that I could find here including Zap the PRAM and Reset the SMC. I also tried the terminal hack with sudo and still no solution. I can't believe both drives have been damaged at the same time. Any other potential solution?

    anybody?

  • External HDs not showing up on computer via firewire and usb

    All external hds do not show up on the computer via firewire or usb. I must have perfomed some updates with my hardware plugged in. Does anybody know how to get this fixed?

    Thought you could use this info about getting FireWire to work!
    First, you should always Repair Permissions in Disk Utility before and after any update; I would do that now. If you installed your update with FireWire plugged in, your Mac may not recognize it anymore.
    Try resetting your FireWire ports by disconnecting all FW devices, shut down your Mac and unplug it from AC power (wall socket) for 30 minutes. plug it back in and try FW.
    If that did'nt work, download the combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try. Yours is the 10.3.9 Combo update. Others reading, download the Combo that applies to your system.
    If that still did'nt get it Zap the PRAM. While restarting Mac hold down the following key combo Command-Option-P-R. Keep holding those keys down till you hear the second start-up chime, then release.
    For those of you with Macs that are not PowerBooks or iBooks, a bad internal battery can cause FireWire to not be recognized, so make sure it's good!
    Good Luck!
    Cheers!

  • 250gb Freecom External Drive not recognised

    I have two 250gb Freecom External Drives. One works fine but the other is no longer being recognised. I have reset PMU and tried to see if the drive is recognised in Disk utility but disk utility simply hangs until i unplug the drive.
    Help!

    i have been experiencing the exact same problem with my external hard drive, except the brand is comstar. perhaps this is a general problem with mac os x and external HDs?

  • External display not recognised in Mountain Lion OS

    Hi all,
    I have a Samsung Syncmaster 2443BW which I wanted to set up as extended display for my new bought Macbook Air.
    I am running the latest Mountain Lion OS including the last updates.
    When attached the monitor with an Apple miniDisplay port to DVI adapter it is not recognised, nor showing up in the System Preferences - displays menu.
    Any help is appreciated - thanks!

    If the system is from Dec. 2011 it either came with DVD discs to reinstall the original shipping version of OS X or it came with Lion preinstalled.
    If Lion then you use the Online Internet Recovery system to reinstall Lion, No Password needed. To boot to the Online system at startup hold downn the Option/Alt + Command + r keys and hold them down until you see a globe on the screen. From the Mac OS X Utilities screen that comes up use Disk Utility to partition the drive as one partition, Formatted Mac OS X Extended (Journaled) with a Partition table of GUID (That is an option under the Options button). Then click the Apply button. Once that is done exit DU and select Reinstall Mac OS X.
    If it came with system Reinstall discs you have to use those to reinstall OS X and the iLife apps then you can use the Mac App Store to upgrade to Lion, Mt Lion or Mavericks. Whichever version you bought from the App store perviously or Mavericks for free.

  • WD external harddisk not recognised after failed format

    Hi folks,
    So I have an old WD 320GB harddisk I pulled from an old windows acer 5535 I wasn't using, I tried formatting it to OSX journaled so i could use it to back my friends mac up. The drive was initially readable and showed my windows 7 and files I had on there.
    I left it to work for a couple of hours, when I came back it said it had failed. I have since read about the 'correct' way to format this drive.
    The drive no longer shows up in disk utility or in system profiler under USB.
    I'm plugging in using a USB SATA enclosure.
    The mac I tried to format on is an old white unibody running 10.6.8, it's not recognised on my imac running 10.8.4.
    The disk spins and the green light on the enclosure is lit.
    Have I killed it or can I save it with some more powerful software?
    Cheers!
    Karl,

    Yes i thought this too, problem is my old acer's GPU is problematic and will only work now and again, I think it needs re-flowing. I'll put the hard drive back and try to get it booted up and see what happens. I'm guessing it's no good now anyway after the mac tried to format it for a while.
    Will report back.
    Karl.

  • External drive not recognised in Finder or Disk Utility on new Mini

    Hi,
    I've just bought a new Mac Mini and it won't recognise my Seagate Expansion drive in either Finder or Disk Utility. The drive is fully accessible on my old Macbook (running Snow Leopard), and ran fine on my old iMac running Mavericks. I've tried the troubleshooting tips in other threads - Seagate External Hard Drive does not work on Yosemite - but since they refer to people upgrading to Yosemite, I'm wondering if this might be down to the hardware in the latest Mini models? Any info or ideas on what to try next would be hugely appreciated!
    Thanks.

    -  Do other external USB drives work on your Mini?
    - If you go to System Report (click on Apple icon in upper left and select About this Mac>More Info>System report) what shows for the drive under Hardware>USB? Yo should see the enclosure chip as well as the drive itself.
    - Tr resetting the SMC and PRAM
    - If you purchased the Mac within the last 90 days you still have free telephone support

  • External Harddrive not recognised on GX740

    Hi,
    Recently my External HD "wesern digital My Book Studio Edition II" does not come up in my GX740 notebook.
    I have tried all usb connections.
    As far as I understand the HD uses windows-drivers, (not from cd)
    The Harddrive works fine on my other computer.
    Does anyone have suggestions what I should do/try to fix?
    Do you think it is a Hardware thing "maybe reinstall usb drivers"
    or maybe a Windows issue??
    Help is appreciated.
    Regards   
    Gunde

    Thank you for the answer.
    Unfortunately the disk is not shown in "ctrl panel / Administrator tools / disk management" so I have nothing to partition, it cant find the disk.
    Also the disk pop up directly when i plug it into my other notebook.
    The computer does make that familiar sound when you plug in a new device in an USB port (on the MSI computer) but maybe that is just the computer recognising that something is plugged in to the usb-port.
    Hopefully somebody can help

    Hi I had the same issue in XP after upgrading to  iTunes ver. 10.7.0.21
    I was in the middle of activating the phone over the air which failed.
    When connecting to iTunes the phone did not get recognised.
    I had to  unplug/replug the usb cable 2x before the device got recognized.
    Must be a windows issue, i suspect.

  • Mac OS 5.8 usb external keyboard not recognised

    I ordered a new mac keyboard and hooked it up with my Kensigton Trackball but they are not being recognised by my macbook.

    From searching the web, I am tempted to say the Iso Gear is quite an exotic device.
    It's up to Astone them to deliver a firmware upgrade for their device to work with Mac OS X 10.5, as Apple probably follows USB 2.0 standards when accepting (or not) an external hard drive.
    diskutil became more picky in 10.5 (been bitten myself) but still, I am not sure whether this is due to Apples development teams faults or due to to Astone following standards.
    There has been an issue in 2006 with LaCie drives on OS X 10.4 which were resolved by their firmware upgrade.
    I know this is of no help to you, but consider not just talking on Apple forums about this but also on Astone help channels.

So I uninstalled and reinstalled the software,,,,,now the hard disk does not appear anymore in disk utilities .....I'm getting futher away from an solution .... :-( what can this be ? ever heard of an problem like this ?  I thank you in advance for taking your time to look into this problem.
